DUST-GUARD FOR CAR-AXLE BOXES.

SPECIFICATION forming part of Letters Patent No. 361,732, dated April 26,1887.

Application filed February 21,1887. Serial No. 228,376.

To aZZ whom, it may concern.-

Be it known that I, FRANKLIN TAYLOR, of Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Dust-Guards for Oar-Axle Boxes, of which the following is a specification.

My invention relates to a dust-guard in which vulcanized fiber or like material is employed in connection with a slab of wood or other similar light material.

I am aware that, broadly, the use of vulcanized fiber for a dust-guard is old. I am also aware that it is old to fasten an apertured sheet of leather upon an apertured board; and in a patent granted to me March 1, 1886, I have shown a dust-guard composed of a ring or apertured piece of vulcanized fiber countersunk into the face of the carrying-board. I do not therefore claim any such subj eat-matter.

My present improved dust-guard consists of an apertured carrying-board having an aperture larger than the journal which passes through it, and a ring or circularly-curved j strip of vulcanized fiber or like material secured within the aperture in the board, so that the only surface presented to the journal is one of vulcanized fiber, and that surface may be in width at least equal to the thickness of the board.

In the accompanying drawings, Figure l is a front elevation, and Fig. 2 a transverse sec-' tion.

A represents a circularly-apertured board, Within the aperture of which is arranged a ring of vulcanized fiber, B. The fiber may be held in place by staples C, which enter the fiber ring and the adjacent part of the board; or any other suitable retaining devices may be employed for firmly securing the ring in place. The staples are preferably arranged upon both (No model.)

nal, and as it may occupy the entire Width of the board a vulcanized-fiber surface equal to the full width of the board may be obtained. The ring also braces and strengthens the board and prevents splitting.

This construction is specially advantageous in those boxes in which the space allowed for the dust-guard is very narrow,because,in such cases, if the vulcanized fiber or like material has to be mounted on one face of the board, and even when countersunk in one face of the board, a contact-surface of fiber of very limited width only can be obtained, whereas with my improved construction the dust-guard may be adapted to the width of the space in the box and afibersurface of the greatest possible width employed.

I claim as my invention The dust-guard herein described,consisting of a carrying-board having an aperture larger than that required for the reception of the axle, and a ring of vulcanized fiber or like material arranged within the aperture in the board, whereby a fiber ring as thick as the board may be used, and the only surface pre sented to the axle may be of fiber.

In testimony whereof I have hereunto subscribed my name.

FRANKLIN TAYLOR.
